There are two other things I'd like to talk about. There are women who come in and have abortions but aren't pregnant. You may say, "Oh, that doesn't happen." Maybe you say that. It does happen. First of all, this woman thinks she's pregnant. She's scheduled herself for an abortion. She's come in and her pregnancy test is negative. They have a woman that they have paid their advertising dollars to get in there. They want to do that abortion if there is any way.
So they do everything they can to prove that she's pregnant or has been pregnant. You say "has been pregnant?" Yes, if they can convince her that she has been pregnant, that she's had a spontaneous abortion. She's going to have to go into the hospital to have a D&C to remove the rest of the contents of her uterus. They will convince her to go ahead and have a procedure she doesn't need that day. And it happens. Channel four [Dallas-FortWorth] got it on tape -- a woman that went directly from our office to a doctor's office and the doctor told her that she was and had never been pregnant, and we had tried to do an abortion on her.
